I mentioned that Holmes and Watson (or Doyle) have some usages which are still criticised as modern abuses or mistakes: "very unique" is one.
I had not noticed native speakers saying "very delicious" until relatively recently - but maybe I just hadn't noticed. On the other hand, I have commented on people saying "absolutely", which used to be one of the few modifiers used with these "ungradables", with normal gradable adjectives: "That's absolutely important", for example.
But Holmes certainly says "very delighted", which seems similar (in "the Stockbroker's Clerk"). So, I will look out for other "modern horrors" from over a hundred years ago. I might even spot a "Yes, no, absolutely, Holmes!"
